    1. Underground tanks (Rectangular or Cylindrical): This type of tank used for storing water initially before lifting it up. This water tank used for fire safety requirements.

    2. Overhead tanks (Circular or Spherical): Overhead Water Tanks can be used in various applications can serve both Domestic purposes and Commercial Purposes. Constantly maintains the flow in all the general bathroom usages and other water requiring appliances through gravitational force.

    3. Tank resting on grounds (Rectangular): A ground water storage tanks (or surface tanks) are used for ground storage of potable drinking water, wastewater, treated water, rainwater collection, etc. And it is designed as crack free structures to eliminate any leakage.

    Underground RCC Water tank construction procedure

    • Excavation should be done as per requirement of the tank size. The top slab of the tank should be 2-3ft high from ground level to resist rain water from entering into tank.
    • The base of excavated area should be levelled and compacted then base slab of tank should be casted after brick soling. Water proofing of concrete required at the time of concreting and plastering.
    • Side walls can be of brick work (10 inch thickness) or RCC wall can be used in both the cases water proofing must be considered.
    • Top slab casting with proper manhole, inlet and outlet connections.

    • As per load of the tank (weight of water and weight of concrete structure) columns are designed and casted with proper bracing.
    • Then water tank is constructed with proper reinforcement (Structural designing of reinforcement must be done). This type of tank is generally constructed in cylindrical shape with cone shaped top and bottom slab.
    • In all type of tanks fittings of inlet, outlet, over flow outlet and manhole with cover must be considered properly. Water proofing required in all sides except top slab. Inside of the tank must be smooth.
